Trinidad and Tobago does not have a comprehensive framework in place that provides effective protection of trade secrets, but there are limited measures addressing some issues related to them. Art. 9 of the Protection Against Unfair Competition Act determines that any act or practice, in the course of industrial or commercial activities, that results in the disclosure, acquisition or use by others of secret information without the consent of the person lawfully in control of that information and in a manner contrary to honest commercial practices shall constitute an act of unfair competition. In addition, Art. 9 defines "secret information" as well as setting out what its disclosure may result from, such as industrial or commercial espionage or breach of contract.

There is an obligation for passive infrastructure sharing in Trinidad and Tobago to deliver telecom services to end users. It is practised in both the mobile and fixed sectors based on commercial agreements. Passive sharing of telecom infrastructure is mandated under Art. 26.1 of the Telecommunications Act of 2001, which was amended in 2004 to include this provision. The document titled Telecommunications (Access to Facilities) Regulations details the regulations for licensees of telecommunications services to negotiate in good faith in order to share the use of their facilities.

The Telecommunications Services of Trinidad and Tobago Limited (TSTT) is jointly owned by National Enterprises Limited (NEL), which in turn is majority owned by the Government of Trinidad and Tobago, and Cable & Wireless (West Indies) Limited (C&W).

TSTT provides the following telecommunications services: mobile telephone, data (domestic and international), voice (domestic and international), internet access and cable TV broadcast.

Trinidad and Tobago mandates functional and accounting separation for operators with significant market power (SMP) in the telecom market. The Accounting Separation Guidelines for the Telecommunications Sector from February 2012 dictate the preparation of separate accounts for each of the different businesses operated by the same concessionaire by identifying and allocating the costs and revenues associated with each business as well as the dealings between them. It sets the guiding principles for this process, which concessionaires must implement. Dominance can be reviewed at any time when deemed necessary or upon the request of an operator. These guidelines are emitted as per Section 24.1 of the Telecommunications Act 2001. Additionally, it is reported that functional separation is also required by law, although the law has not been identified.

According to Art. 5 of the Foreign Investment Act, foreign entities must secure a license to hold more than 30% of the shares in any public company, a stipulation that extends to entities within the telecommunications sector. Furthermore, obtaining this license is subject to additional constraints, which include, inter alia, the fulfilment of minimum capital requirements established by the regulatory framework.

According to Art. 10 and 11, the act protects works for the sole fact of their creation irrespective of their mode or form of expression, as well as of their content, quality and purpose. The law establishes and regulates a series of exceptions for the use of copyrighted work, in which protected works may be used without the authorisation of the owner of the copyright and payment of compensation. These are as follows:
- Private reproduction for personal purposes, as per Art. 9;

Copyright is not adequately enforced online in Trinidad and Tobago. It is reported that there are concerns about Trinidad and Tobago piracy for optical disc music and video, non-payment of copyright royalties, and online piracy. It has also been reported that copyright owners face serious challenges in protecting their copyright. While members of the industry believe there are sufficient laws to prevent piracy and copyright infringement, local creators are unwilling to engage in convoluted legal battles due to the non-recognition of the value of their intellectual property. In 2022, the Telecommunications Authority of Trinidad and Tobago (TATT) conducted audits on compliance with its concessions agreement requiring domestic broadcasters to respect intellectual property (IP). However, of concern is the lack of enforcement action against the two state-owned telecommunications networks that remain in breach of the agreement, both of which broadcast unlicensed over-the-air content as part of their commercial television subscription packages.

Trinidad and Tobago has ratified the World Intellectual Property Organization (WIPO) Copyright Treaty.
